摘要
研究以三轴地层应力模型为依据 ,从岩石力学破裂作用的原理出发 ,利用长源距声波、体积密度测井、成像测井等资料 ,结合工区实际情况 ,建立计算出岩石闭合压力和岩石破裂压力模型 ,预测出压裂缝高度 ,为现场压裂施工提供了重要的参考依据 ,并见到了较好的应用效果。
Based on triaxial geostress model,the fracturing principle of rock mechanics and considered the reservoir environments, data of long spaced acoustilog,volume density log and imaging log are used to establish math models for calculation of rock closure pressure and rock fracturing pressure, as well as for forecast of the fracturing height to provide important fracturing parameters for in-situ fracturing operation, the result of which is better.
